install amd driver on ubuntu 20.04

I have amd radeon hd 4350/4550 gpu,and I'm on ubuntu 20.04. so I tried many way to install official amd driver for ubuntu but every time I get an error. for example: I downloaded amd driver form amd.com and i going to install requairment befor install it.

kernel@kernel-EP43-UD3L:~$ sudo apt-get install linux-headers-generic build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases
[sudo] password for kernel:

This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'libqtgui4' has no installation candidate
E: Unable to locate package libelfg0

I get an error,what can i do for resolve it?

One problem might be that Ubuntu 20 ships with kernel version 5.4. The kernel for your driver is limited to 3.4. Might need a different Ubuntu dist? Or maybe time for a GPU upgrade? Either way, that's probably your main issue.

I've successfully installed AMD drivers on Ubuntu 20.04 for the following cards:

• 5500 XT
• RX Vega 64

I know those cards use a different driver, so adjust the naming convention(s) accordingly. Maybe this will be helpful for someone else.

Let's get a clean install, first.

locate amdgpu-uninstall

Should be /usr/bin/amdgpu-uninstall...run it.

sudo /usr/bin/amdgpu-uninstall

If it fails to delete /opt/amdgpu/ and/or /opt/amdgpu-pro/ directories, then:

sudo rm -rf /opt/amd...

Here is your driver:

You'll need to unzip it.

sudo apt-get install unzip
unzip ~/Downloads/amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.zip
./amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.run

Current AMD Driver

Again, wrong kernel, so this is probably moot.

You could try giving a different driver a whirl?

Alternatively: Check here

tar -xvf ~/Downloads/amdgpu-pro-21.30-1290604-ubuntu-20.04.tar.xz
sudo ./amdgpu-pro-21.30-1290604-ubuntu-20.04/amdgpu-install --opencl=pal,legacy,rocr --no-dkms --headless

Groups

Add yourself to render and video groups

sudo usermod -aG render $USER
sudo usermod -aG video $USER
sudo reboot

Changes won't take affect until you reboot.

Finally...

Darktable

Darktable Benchmark

sudo apt install darktable
sudo darktable-cltest

Linux Firmware

This might also be helpful

git clone
sudo cp ~/linux-firmware/amdgpu/* /lib/firmware/amdgpu && sudo update-initramfs -k all -u -v

Good luck.

May the odds be forever in your favor.

One of many sources:

Ubuntu drivers

The providing package for the driver is xserver-xorg-video-radeon_19.1.0-1_amd64, so you should install it with sudo apt install xserver-xorg-video-radeon_19.1.0-1_amd64 (apt-get is disfavored). This should work out-of-the-box.

Proprietary drivers

If you want to go with proprietary drivers, there is a simple guide. Go to the AMD Download Page, and grab the latest version of the drivers that matches your card. Then execute (with suitable version numbers)

$ tar -xf amdgpu-pro_*.tar.xz
$ cd amdgpu-pro-XX.XX-XXXXXX
$ ./amdgpu-pro-install -y

Third party repository

To have the latest AMD Radeon driver version execute

$ sudo add-apt-repository ppa:oibaf/graphics-drivers
$ sudo apt update && sudo apt -y upgrade

TL;DR:

Ubuntu drivers

From

NOTE: For Ubuntu 16.04 LTS and above, the AMD Catalyst or fglrx driver is no longer supported by AMD, or in Ubuntu.{1} If you have an AMD GPU and wish to run any Ubuntu version 16.04 LTS or newer, there are two open source driver options: Radeon or AMDGPU. The AMDGPU-PRO driver provides the open source AMDGPU driver and a proprietary overlay. Newer AMD GPUs designed with GCN technology (Graphics Core Next) should use AMDGPU or AMDGPU-PRO, while older AMD GPUs should use Radeon.

For the graphics card Radeon HD 4350/4550 the chipset is RV710.

According to this official info (or man radeon), that card/chipset is in the list of SUPPORTED HARDWARE by the radeon Xorg driver, with the following features:

1. Full support for 8-, 15-, 16- and 24-bit pixel depths, and for 30-bit depth on Linux 3.16 and later;
2. RandR 1.2 and RandR 1.3 support;
3. Full EXA 2D acceleration;
4. Textured XVideo acceleration including anti-tearing support (Bicubic filtering only available on R/RV3xx, R/RV/RS4xx, R/RV5xx, and RS6xx/RS740);
5. 3D acceleration;

The providing package is xserver-xorg-video-radeon_19.1.0-1_amd64, so you should install it with sudo apt install xserver-xorg-video-radeon_19.1.0-1_amd64 (apt-get is disfavored). This should work out-of-the-box.

The problem you are quoting in the OP is 'libqtgui4' has no installation candidate.

What makes you think you need it to have the right amd drivers for your card? Where did you get such info/hint? What about the other packages you are installing?

I suggest you go over the following commands one by one, and post the output in the OP, by copy-pasting text, not screen capture. That will help solving potential problems in case the solution does not work.

$ sudo update-pciids
$ lspci -nn | grep -E 'VGA|Display'
$ dmesg | egrep -i 'drm|radeon'
$ sudo lshw -c video
$ lsmod | grep amd
$ glxinfo -B

Note: This is perhaps an alternative, YMMV.
